>If Bochs is compiled with cpu level 5 or higher the CPUID opcode is supported
and it can return some information about the cpu model and it's features. When
using a pre-defined CPU model in Bochs the features reported by CPUID are set up
according to the model's specification. The following table shows all available
CPU models with a short description. The amount of choices depends on the CPU
features enabled at compile time (3rd column).</P
